Cala Ostina: Weather Today

📅 Thursday, May 7, 2026
Today is unfortunately not an ideal day for a beach visit to Cala Ostina. The sky remains heavily obscured by thick fog, and the persistent cloud cover means you will miss out on the warmth of the sun. While the air temperature reaches 22.1 °C, the conditions feel quite damp and gray rather than inviting. With the sea temperature sitting at 17.9 °C, the water is definitely too cold for comfortable swimming. You should also be aware that the wind is quite active today, creating somewhat choppy conditions along the shore. If you do head out, please note that the UV Index is 7, so protection is still necessary despite the lack of direct sunshine. It is best to save your beach trip for a clearer, calmer day.
